4 Claims.

The present invention relates to new and useful improvements in orangeparers of the type constituting the subject matter of U. S. Patent No.1,008,555, and has for one of its important "5 objects to provide, in amanner as hereinafter set forth, a parer of this character embodyingnovel means for automatically returning the knifeto its startingposition.

Other objects of the invention are to provide a l0 parerof theaforementioned character which will be simple in construction, strong,durable, highly eiiicient and reliable in use, compact, and which may bemanufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a top plan View of an orange parer constructed in accordancewith the present invention.

Figure 2 is a View in front elevation thereof.

Figure 3 is an end elevational View.

Figure 4 is a view in vertical transverse section, taken substantiallyon the line 4-4 of Figure 2.

Figure 5 is a View in horizontal section, taken substantially on theline 5 5 of Figure 2.

Figure 6 is a vertical sectional view through the knife, takensubstantially on the line 6-5 of Figure 2.

Figure 7 is a View in horizontal section through 85' the knife, takensubstantially on the line 7 7 of Figure 2.

Figure 8 is a detail view in plan of the lever constituting an elementof the knife returning mechanism.

Figure 9 is a detail View in elevation of another lever constituting oneof the elements of the knife returning mechanism.

Figure 10 is a View in front elevation of the swinging knife supportingarm.

Figure 11 is a detail View in side elevation of the knife supportingarm.

Figure 12 is a detail view in front elevation of the slidable bearing inwhich the knife supporting arm is journaled.

Referring now to the drawings in detail, it will be seen that theembodiment of the present irvention which has been illustrated comprisesa frame 1, which, as best seen in Figure 2 of the drawings, issubstantially U-shaped in front ele- 55 vation, said frame beingprovided with a Suit- (Cl. 14S-43) able clamp 2 for securing the pareron a table or 3 other support. Journaled longitudinally in the frame 1is a worm shaft 3 which is driven by a hand crank 4 and which has fixedthereon a gear 5. v

Holders 6 and 7 are mounted on the frame 1 in opposed relation to eachother for securing an orange therebetween, the holder 6 being mounted onone end of a longitudinally slidable shaft 8 for movement in ahorizontal plane toward and away from the holder 7. A handle 9 isrotatably mounted on the other end of the shaft 8. The holder 7 is fixedon one end of a shaft 10 which is journaled in a bearing providedtherefor 'on the frame 1, a gear 11 being xed on the other endportionpof said shaft 10. The gear 11 is meshed with the comparativelylarge gear 5 for actuation thereby. Teeth 12 are provided on the holders6 and 7 for penetrating the rind of the orange.

Depending from an intermediate portion of the frame 1 are spaced,opposed, integral guides 13 in which a vertical bearing 14 is mountedfor sliding movement in a horizontal plane. Journaled in the rbearing 14is an angular arm 15 having a gear segment 16 on one end for operativeengagement with the worm shaft 3. On the other end of the angular arm 15are ears 17 between which a stem 18 is journaled for swinging movementin a vertical plane. A spring 19 is provided for yieldingly urging thestem 18 toward the orange between the holders 6 and 7 and a spring 20 ismounted on the slidable bearing 14 and engaged with the arm 15 foryieldingly urging said arm toward its retracted or starting position. Apull spring 21 is connected with the bearing 14 for yieldingly urgingsaid bearing in a direction to engage the segmental gear 16 with theworm shaft 3. The reference numeral 22 designates an adjustable stop forthe stem 18 which is threadedly mounted in the arm 15.

The upper portion of the stem 18 is threaded for adjustably supporting aknife which is designated generally by the reference numeral A28. Asillustrated to advantage in Figures 6 and 7 of the drawing, the knife 23comprises a block 24 which is secured in adjusted position on the stem18 by a set screw 25. A lock nut 26 is engaged with the lower side ofthe block 24. Mounted on the block 24 is a substantially U-shaped blade27 which is secured to said block, as at 28. The reference numeral 29designates a gage which is mounted on top of the block 24, said gagehaving a slot 30 therein which accommodates the stem 18 and whichpermits adjustment. The gage 29 is secured in adjusted position by awinged nut 31 which is threaded on the stem 18.

Pivotally mounted, at an intermediate point, beneath the frame 1 is anangular lever 32 which is operatively engaged with the slidable bearing14 for shifting said bearing against tension of the spring 21. The otherend portion of the lever 32 is in the path of a nger 33 which projectsfrom the arm 15. Mounted for sliding movement in one of the guides 13 isa spring actuated latch 34 which is engageable in a recess 35 providedtherefor in one side of the slidable bearing 14. The latch 34 isoperatively connected with a lever 36 which is pivotally connected, atone end, to the frame 1. The other end portion of the lever 36 extendsangularly and terminates in a cam 37 which is positioned for engagementby a nger 38 which extends angularly from the adjacent edge of the arm15. The reference numeral 39 designates stops which are provided in theguides 13 for limiting movement of the slidable bearing 14 underimpulsion of the spring 21.

Briefly, the operation of the parer is as follows: The orange is clampedbetween the holders 6 and 7 and the crank 4 is then actuated to rotatesaid orange and the shaft 3. Rotation of the shaft 3 swings the arm 15from right to left, the gear segment 16 being maintained in engagementwith said shaft 3 by the spring 21. The spring 19 maintains the knife 23in engagement with the orange for removing the rind. As the knife 23approaches the limit of its movement in this direction, the nger 33engages the lever 32 and actuates said lever in a direction to shift theslidable bearing 14 against the tension of the spring 21 for disengagingthe gear segment 16 from the worm shaft 3. Of course, movement of thearm 15 from right to left i'ncreases the tension of the spring 20 andwhen the gear 16 is disengaged from the worm shaft 3 said spring 20returns the arm 15, and consequently the knife 23, to their startingpositions. When the lever 32 shifts the slidable bearing 14 to disengagethe gear segment from the shaft 3 the latch 34 engages in the recess 35which is provided therefor in said slidable bearing for maintaining thegear 16 in disengaged position during the return movement of the knife.As the knife approaches its starting point, the finger 33 engages theend 37 of the lever 36 and actuates said lever in a manner to retractthe latch 34, thus permitting the spring 21 to shift the bearing 14 foragain engaging the gear 16 with the worm shaft 3.

As illustrated to advantage in Figure 1 of the drawings, the segmentalgear 16 includes a comparatively high end tooth 40. This comparativelyhigh tooth 40 engages with the worm shaft 3 at substantially the sametime that the lever 32 shifts the bearing 14 for disengaging thesegmental gear 16 from the worm shaft 3, thus assuring ample clearancefor the teeth of said gear 16 during the return movement of the knife.

It is believed that the many advantages of an orange parer constructedin accordance with the present invention will be readily understood, andalthough the preferred embodiment of the invention is as illustrated anddescribed, it is to be understood that changes in the details ofconstruction and in the combination and arrangement of parts may beresorted to which will fall within the scope of the invention asclaimed.
